1. The first part of my 90 minute tutorial, Manipulating 3D Space with Expressions in After Effects

A 2 minute introduction to the full tutorial, just to whet the appetite!

2. The second part of my 90 minute tutorial, Manipulating 3D Space with Expressions.

In this 6 minute section, I'll be looking at the basic principles of the After Effects coordinate system. I'll explore world space, layer space and (to a lesser extent) compostion space by using a simple demonstration. It's essential to understand these coordinate systems, because the toWorld and fromWorld methods that I take a look at in a later part of this tutorial are used specifically to switch between world space and layer space.

3. The third part of my 90 minute tutorial, Manipulating 3D Space with Expressions.

In this 18 minute section, I'll be setting up a simple system and using some expressions to help with intuitively visualizing how After Effects coordinates work, and to show the basics of how we can use expressions to measure a layer's position in various different spaces.

4. The fourth part of my 90 minute tutorial, Manipulating 3D Space with Expressions.

In this 8 minute section, I'll be setting using the stuff that I looked at in parts 1-3, to make a simple practical example, of automatically focussing a camera on a 3D object, regardless of the parenting set-up of the camera or the object.

5. The fifth part of my 90 minute tutorial, Manipulating 3D Space with Expressions.

In this 30 minute section, I'll be looking at another real world example using the toWorld and fromWorld layer space transforms to make a system that uses nulls as targets for spotlights and camera - and in such a way that the system is completely robust - it works however you choose to change parent-child relationships after you've set it up.

This is a series of tutorials that deals in depth with the concepts and practicalities of using expressions to manipulate 3D space in After Effects. The emphasis is very much on acquiring a deep understanding of the concepts via visual demonstrations of principles... and of practical examples that put those concepts into use in various ways.

The first two volumes are finished and consist of 6 and 4 parts respectively (in total so far, 3 hours of tutorial).

The first volume deals with the layer space transforms toWorld() and fromWorld()
The second volume deals with the layer space transforms toWorldVec() and fromWorldVec()

I'm ultimately intending this to consist of five or six volumes, but that all depends on time. :-)
